Summary Sarcocystosis is a parasitic disease caused by varying Sarcocystis species infecting humans and animals. It is commonly found in small ruminants causing pathogenic effects. This contributes to detrimental economic loss for local farmers and the local economy due this disease. Although the distribution of Sarcocystis can be found all over the world, the species infecting small ruminants in Tunisia is still unknown. Through this study, we aim to estimate the molecular prevalence of natural infection with Sarcocystis spp. in sheep and goats using molecular identification. Also, phylogenetic analyses were used to identify the different species of this parasite infecting small ruminants in northern Tunisia for the first time. DNA was extracted from 198 and 121, sheep and goats meat samples, respectively. The molecular prevalence of Sarcocystis spp. in sheep and goats was 58.6% (116/198) and 50.4% (61/121), respectively. Compared to the Noire de Thibar and cross‐breeds, the Barbarine sheep had the highest infection prevalence (63.4%) ( p = .004). Five of the 116 positive samples were sequenced identifying Sarcocystis tenella from sheep. For goats, the sequencing results showed that five positive PCR products belonged to Sarcocystis capracanis species.
